I agree with you on Justine. But the Williams Sisters - earlier Venus and now Serena have been number one for a decade. That pretty long time in tennis even going back before the Open Era. Steffi, Navratilova, Evert were pretty consistent top players too. Victoria Azarenka for 2011-2012 seem unbeatable - that because Serena was injury first half of the year. Women game now is based on consistence vs. power. You have to have both to win and be at the top! Same with the men too.

not surprised at all. The WTA is a complete mess I'd rather watch curling or poker on TV than women playing tennis. Woz has no weapons, she can only defend, push, grind .... whatever, very boring player.
